Jon Hamilton

Jon Hamilton is a correspondent for NPR's Science Desk. Currently he focuses on neuroscience and health risks.

In 2014, Hamilton went to Liberia as part of the NPR team that covered Ebola. The team received a Peabody Award for its coverage.

Following the 2011 earthquake and tsunami in Japan, Hamilton was part of NPR's team of science reporters and editors who went to Japan to cover the crisis at the Fukushima Dai-ichi nuclear power plant.

Hamilton contributed several pieces to the Science Desk series "The Human Edge," which looked at what makes people the most versatile and powerful species on Earth. His reporting explained how humans use stories, how the highly evolved human brain is made from primitive parts, and what autism reveals about humans' social brains.

In 2009, Hamilton received the Michael E. DeBakey Journalism Award for his piece on the neuroscience behind treating autism.

Before joining NPR in 1998, Hamilton was a media fellow with the Henry J. Kaiser Family Foundation studying health policy issues. He reported on states that have improved their Medicaid programs for the poor by enrolling beneficiaries in private HMOs.

From 1995-1997, Hamilton wrote on health and medical topics as a freelance writer, after having been a medical reporter for both The Commercial Appeal and Physician's Weekly.

Hamilton graduated with honors from Oberlin College in Ohio with a Bachelor of Arts in English. As a student, he was the editor of the Oberlin Review student newspaper. He earned his master's degree in journalism from Columbia University, where he graduated with honors. During his time at Columbia, Hamilton was awarded the Baker Prize for magazine writing and earned a Sherwood traveling fellowship.

The Food and Drug Administration has approved a variant of the anesthetic and party drug ketamine for suicidal patients with major depression.

The drug is a nasal spray called Spravato and it contains esketamine, a chemical cousin of ketamine.

STACEY VANEK SMITH, HOST:

This is the story of a fatal genetic disease, a tenacious scientist and a family that never lost hope.

Conner Curran was 4 years old when he was diagnosed with Duchenne muscular dystrophy, a genetic disease that causes muscles to waste away.

Conner's mother, Jessica Curran, remembers some advice she got from the doctor who made that 2015 diagnosis: "Take your son home, love him, take him on trips while he's walking, give him a good life and enjoy him because there are really not many options right now."

For years, public health officials have been trying to dispel the myth that people who get a flu shot are more likely to get Alzheimer's disease.

They are not. And now there is evidence that vaccines that protect against the flu and pneumonia may actually protect people from Alzheimer's, too.

The same process that causes dew drops to form on a blade of grass appears to play an important role in Alzheimer's disease and other brain diseases.

Scientists are monitoring the virus that causes COVID-19 for genetic changes that could make a vaccine ineffective. But so far, they're not seeing any.

ARI SHAPIRO, HOST:

Three research institutions in Seattle have joined forces to study how Alzheimer's disease takes root in the brain.

The consortium will create a new research center at the Allen Institute for Brain Science to study tissue from brains donated by people who died with Alzheimer's.

A neurologist who encased his healthy right arm in a pink fiberglass cast for two weeks has shown how quickly the brain can change after an injury or illness.

Daily scans of Dr. Nico Dosenbach's brain showed that circuits controlling his immobilized arm disconnected from the body's motor system within 48 hours.

But during the same period, his brain began to produce new signals seemingly meant to keep those circuits intact and ready to reconnect quickly with the unused limb.

NPR's Ari Shapiro and Michel Martin are joined by NPR's science correspondent Jon Hamilton to talk about the information about the coronavirus learned since the beginning of the pandemic.

Mounting evidence suggests the coronavirus is more common and less deadly than it first appeared.

The evidence comes from tests that detect antibodies to the coronavirus in a person's blood rather than the virus itself.

The tests are finding large numbers of people in the U.S. who were infected but never became seriously ill. And when these mild infections are included in coronavirus statistics, the virus appears less dangerous.

COVID-19 has given ventilators an undeservedly bad reputation, says Dr. Colin Cooke, an associate professor of medicine in the division of pulmonary and critical care at the University of Michigan.

"It's always disheartening to know that some people are out there saying if you end up on a ventilator it's a death sentence, which is not what we are experiencing — and I don't think it's what the data are showing," Cooke says.

Intensive care teams inside hospitals are rapidly altering the way they care for patients with COVID-19.

The changes range from new protective gear to new treatment protocols aimed at preventing deadly blood clots.

When COVID-19 patients began flooding emergency departments at New York hospitals in March, doctors saw some unusual cases of stroke.

"We had a young woman in her early 30s who came in with a profound stroke, the kind of stroke that leaves someone permanently paralyzed and possibly unable to survive," says Dr. J. Mocco, a professor of neurosurgery and director of the cerebrovascular center at Mount Sinai Health System in New York.

On April 8, David Williams got a standing ovation as he was wheeled out of the John L. McClellan Memorial Veteran's Hospital in Little Rock, Ark.

Williams, 54, a Marine Corps veteran, had survived eight perilous days on a ventilator with COVID-19, and the hospital staff had lined up to give him a joyous, fist-bumping send-off.

Today, Williams is back at home with his wife, D'Anna. But a full recovery remains a distant prospect.

MICHEL MARTIN, HOST:

Most coronavirus patients who end up on ventilators go on to die, according to several small studies from the U.S., China and Europe.

And many of the patients who continue to live can't be taken off the mechanical breathing machines.

"It's very concerning to see how many patients who require ventilation do not make it out of the hospital," says Dr. Tiffany Osborn, a critical care specialist at Washington University in St. Louis who has been caring for coronavirus patients at Barnes-Jewish Hospital.

The coronavirus has brought a lot of attention to breathing machines known as ventilators. The devices can be lifesaving for some critically ill patients. But as NPR's Jon Hamilton reports, they're no panacea.
